Vintage Campy BB axel question.

If I want to occasionally swap out my vintage Record double crankset with a triple for more hilly events all I need to do is find an axel to swap out, right? I can still use the existing cups?

The frame has an Italian shell so I'm looking for a "70 SS 120 X3" axle.

Not quite. The actual factual Campagnolo x3 triple BB used the thin cups. There may be other spindles (Sugino?) that would swap in using the thick/rifled cups, but I'm not sure.

Mix and match, hunt and peck, follow the yellow brick road, etc.

A trip to the co-op for a fist full of spindles, then follow the above.

As @jeirvine noted, whether a simple spindle swap would work depends on the cups. The Record triple spindle was only made to use Record ("thin") cups. If your bottom bracket has Nuovo Record ("thick") cups with rifling in the spindle aperture, it won't work. And if the arms are post-CSPC production, they won't work well on a pre-CSPC spindle. There's a lot going on with vintage Campagnolo bottom brackets. Campagnolo USA published an article to make some sense of it:

I also thought it would be a simple spindle swap (NR double to NR triple). Definitely doesn't work. I'm sure the look on my face was priceless "Why isn't this fitting, what's wrong". I was able kludge it with one thin cup as I waited for the second thin cup to come in (one from LBS one from eBAY).
